United States Patent 6 SEAM-OPERATED STOPPING MECHANISM FOR A TEXTILE MACHINE Leland F. Remington, Worcester, Mass., assignor to Curtis & Marble Machine Company, Worcester, Mass, a corporation of Massachusetts Application February 21, 1957, Serial No. 641,674

1 Claim. (Cl. 200-6113) This invention relates to textile machines, such as folding or cloth-inspecting machines, in which successive pieces of seam-connected cloth are drawn over a supporting table or apron.

It is desired under certain operating conditions that the machine be stopped whenever a seam appears on the table, so that the successive pieces of cloth may be separated. To the accomplishment of this general object, my invention relates to the provision of a very simple and reliable mechanism by which the advent of a seam may be promptly indicated, and by which the machine may be promptly brought to rest.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly set forth in the appended claim.

A preferred form of the invention is shown in the drawings, in which Fig. 1 is a partial plan view of a machine having my improvement applied thereto;

Fig. 2 is a side elevation, looking in the direction of the arrow 2 in Fig. 1;

Fig. 3 is an end view, looking in the direction of the arrow 3 in Fig. 2; and

Fig. 4 is an enlarged partial sectional side elevation.

Referring to the drawings, I have shown parts of a folding or inspecting machine including a supporting frame or table and a guide-roll 11 over which the cloth C may be guided for inspection or other purposes. Successive pieces of cloth are indicated as connected by seam S.

My improved seam-indicating mechanism comprises a 2,836,668 Patented May 27, 1958 tube 20 extending across the table 10 and having gudgeons rotatably supported in fixed bearings 22 at the sides of the machine. An eccentric collar 24 is mounted on the tube 20 near the middle portion thereof and may be secured thereon in a desired angular position by a setscrew 25.

An arm 30 is mounted on an extension 31 of one gudgeon of the tube 20, and this arm is provided with an adjustable contact screw 33, normally resting on the spring-supported upper end 35 of a switch 37.

The lower portion of the eccentric collar 24 is to be so positioned as to slightly clear the cloth C as it passes under the collar 24. But if a seam S engages the collar 24, the collar will be turned clockwise as indicated by the arrow in Fig. 4, and the screw 33 will be depressed, thus closing the switch 37 and activating any desired stopping mechanism indicated generally at M in Fig. 2.

The detailed construction of the stopping mechanism forms no part of my present invention and any usual or commercial stopping mechanism may be provided.

It will be noted that the collar 24 is of limited length, so that it engages only a small portion of the width of the cloth C and at approximately the center of its width. The device is thus not likely to be accidentally tripped by slugs or knots which might appear inadvertently at transversely separated points in the Width of the cloth.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claim, but what I claim is:

Seam-operated stopping mechanism for a textile machine in which cloth is drawn over a supporting surface, said mechanism comprising a shaft overlying the cloth, an eccentric collar, means to secure said collar in angularly-adjusted position on said shaft, a control switch, a switch-closing means fixed on said shaft and rendered operative by angular displacement of said shaft by engagement of said collar by a scam in the cloth, and a device to adjust said switch-closing means.
